I like to start by microwaving the potatoes for a few minutes;
it just speeds up the barbequing process. Poke a few holes in each potato then
cook in the microwave on high for 2-3 minutes until they just start to soften,
not too much.

Cut your potatoes in slices about ¼ inch thick.

Cut 2-4 pieces of tin foil, you want the pieces to be double
thick so fold the piece of foil over.

Drizzle on a little olive oil on the center of the tin foil.
Place the potato slices on in an even thin layer, add some onion and
mushrooms. Season the veggies with
seasoning salt and pepper to taste. Place about 1 tablespoon of butter on each
potato.

Fold the foil around the potatoes to make a neat pouch.

Cook on the barbeque on medium high heat for 15-20 minutes
until the potatoes are tender and starting to brown. You will need to flip the
foil pouches over about halfway through.

Serve with a little sour cream.

I love these potatoes! You can add whatever veggies you like
to the packs, I just happen to love mushrooms, but you can skip them if you
want to.
